CLOTH-FINISHIN G.

T 0 all whom it may concern:

Be it known that I, GUSTAV IVoLF, a citizen of the United States, residing at East Providence, in the county of Providence and State of Rhode Island, have invented new and useful Improvements in Cloth-Finishing, of which the following is aspecification.

This invention relates to certain new and useful improvements in cloth finishing, and the primary object thereof is to provide means for producing a sheen or silk-like surface on the cloth.

The invention aims to provide means for expeditiously and economically producing a sheen or silk appearing surface, and briefly involves the passing of the cloth between a heavy top roll and a soft under roll, the upper roll having teeth of such pitch and form so as to close the filling yarn of the cloth to thereby produce additional sunken lines or parts.

In the drawings:

Figure 1 is a vertical sectional view of the invention, and

Fig. 2 is a side elevation partly broken away and in section.

In proceeding in accordance with the present invention an under roll 1 is employed, the surface or periphery of which is covered with felt 2 or other suitable soft material or substance. The upper roll 3 is preferably made of metal and has spiral like teeth extending about its periphery, the pitch of the teeth being such so as to close the filling yarn of the cloth to produce sunken lines. This is accomplished by forming the teeth with alternating deep formations 4 and. shallowformations 5. In other words there are high and low teeth or edges, which teeth or edges alternate and are each of spiral form.

As is apparent from Fig. 2 of the drawings,-

the cloth C as it passes between the rolls is engaged by the teeth 4 and 5 and gathered or forced by the high teeth toward the low teeth, and against the latter, this producing or effecting what might be termed a three point contact with the cloth, so as to produce sunken lines therein. As is apparent from Fig. 2 of the drawings the teeth press the cloth into the material of the lower roller, which material as above stated is of felt'or equivalent soft nature so as to allow the teeth to form undulations in the cloth as above stated.

Specification of Letters Patent.

Patented Dec. 27, 1921.

Application filed August 2, 1921. Serial No. 489,229.

From the foregoing it will beseen that the invention merely requires rotating means of any suitable nature for the roll,

and the feeding of the cloth between such rolls, whereby sunken lines will be produced across the surface of the cloth by gathering the latter as is evident from Fig. 2 of the drawings. The invention can be thus economically produced and easily and quickly operated so as to provide for a large output.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent is 1. In a cloth finishing device, a lower roll having a felt covering, and an upper roll having metallic teeth of spiral form and arranged to be of alternating depths, whereby to provide a three point contact with the cloth.

2. In a cloth finishing device, a lower roll having a felt covering, and an upper metal roll having spiral teeth arranged to provide a three pointcontact with the cloth.

.3. In a cloth finishing device, cloth engaging means, and a roll having spiral teeth of alternating depths whereby to provide a three point contact with the cloth while the cloth is engaged with said means.

4. In a cloth finishing device, cloth engaging means, and a roll having spiral teeth to provide a three point contact with the cloth while the latter is in engagement with said means.

5. In a cloth finishing device, cloth engaging means, and a roll having spiral teeth of varying depths to form sunken wavy lines in the cloth to impart a sheen appearance to the cloth.

6. The herein described method of imparting a sheen appearance to cloth which consists in subjecting the surface of the cloth to pressure on opposite sides thereof and in indenting same to form wavy sunken lines in the cloth of varying depths to impart a sheen appearance to the cloth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GUSTAV WOLF.
